EleventhHourI appreciate the skittles reference
Is it a skittles reference or is it a reference to purple not being an actual color and thus not a part of the rainbow?
the heck do you mean purple is not an actual colour??
Purple, the color directly between red and blue, is a creation of your mind interpreting a band of light that triggers your red and blue sensing nerves, but no green is sensed. The actual band of light we can see goes from red to green to blue. Purple doesn’t fall between those colors, meaning it wouldn’t be included in a rainbow, and isn’t any “pure” light you could see, since it doesn’t fall on the spectrum.
What is violet at the end of the visible spectrum, then? We call the higher wavelength stuff ultraviolet, and violet looks purple to me, so I’m having trouble reconciling this stuff with what you’re saying.
We call it that but our eyes see the far end frequency as a colour that only very slightly activates blue sensitive cone receptors and no others. For red sensitive cones there is a slight bump in the high end frequencies also that makes it possible for them to look violet as it activates the blue sensitive and a bit of red sensitive receptors but a much purpler purple is made by combining high and low frequencies
There is evidence to show that violet does actually weakly activates red cones too. This is because the violet light starts creeping up to double the frequency of the lower end of the red sensitivity, and so it can actually successfully activate it very weakly. There are other factors that can lessen or even fully negate that effect though, it’s all kind of fuzzy.
Violet is dark spectral blue, added as a separate color by people who wanted 7 not six colors in the spectrum
You’re thinking of indigo.
Red
Orange
Yellow
Green
Blue
Violet
That’s 6.
Perhaps it was the number I misremembered. There definitely is no violet in the spectrum
